RFID tag-containing apparatus

Description

BACKGROUND OF THE INVENTION

Field of the Invention

[0001] The present invention relates to an RFID tag-containing apparatus, which is capable of alerting a user to unintended reading of RFID tag information by a third party.

Description of the Related Art

[0002] In recent years, RFID tags (Radio Frequency ID tags) also called wireless IC tags have been widely used in sales management, inventory management, or distribution management. In general, an RFID tag is comprised of a small-sized IC chip and a metal antenna, and the IC chip has a size of 0.1 to several mm square. Each RFID tag can be assigned a unique ID. Further, it is possible to collectively write or read data in or from a plurality of RFID tags from a place somewhat remote from the RFID tags.

[0003] Many RFID tags are provided with a memory, a logic circuit, and coils, and are capable of reading and writing data by wireless communications. Further, they are capable of performing processing, such as computation, authentication, and encryption, using the logic circuit. A device that reads and writes data is called a reader/writer. The reader/writer is capable of performing wireless communications from a location at a distance of several centimeters to several meters.

[0004] Further, some RFID tags have a built-in battery, and others not. The RFID tags without a built-in battery are supplied with power by receiving radio waves from the reader/writer or a RFID tag reader. On the other hand, the RFID tags with a built-in battery are capable of actively transmitting information.

[0005] As mentioned above, RFID tags are used for various applications and it is expected that the use of RFID tags will further expand in the future. However, if a malicious third party reads information stored in an RFID tag attached to an article which the user is carrying with him/her, the information can be used for undesirable purposes. For this reason, the development of an apparatus or device is desired which can prevent unintended reading of such information by a third party.

[0006] A system disclosed in Japanese Laid-Open Patent Publication (Kokai) No. 2003-123040 is provided with authentication means for determining whether or not reading of information should be permitted. This system allows reading of only information approved by the authentication means for reading.

[0007] However, in this conventional system disclosed in Japanese Laid-Open Patent Publication (Kokai) No. 2003-123040, since the authentication means is provided in an RFID tag itself, the RFID tag inevitably becomes larger in size and higher in cost. Further, general-purpose RFID tags without the authentication means are incapable of even alerting the user to leakage of data.

[0008] US published patent application US 2003/076230 A1 discloses a system for reducing security risks wherein a centrally installed control/interrogation apparatus actively sends out interrogation signals upon a certain event, i.e. a person approaching a door, in order to detect whether security sensitive items equipped with an RFID tag are present in a room outside a shielded safe or vault. If a return signal is received in response to the active interrogation signal, an alert or alarm is signaled.

[0009] US published patent application US 2004/100383 A1 discloses labeling products with RFID smart tags and employing a smart tag scanner in order to determine, whether the labelled products are stored in the proper location.

[0010] German published patent application DE 101 11 063 A1 discloses a shielded case for a mobile phone, wherein an incoming call notifying device is disposed outside the case. Japanese publication JP 2004-188215 discloses a shielded case for protecting data on a noncontact type IC-card.

SUMMARY OF THE INVENTION

[0011] It is an object of the present invention to provide an RFID tag-containing apparatus which is capable of alerting a user to leakage of information stored in RFID tags without tailoring the RFID tags.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] The present invention will now be described in detail below with reference to the drawings showing preferred embodiments thereof.

[0022] FIG. 4 is a perspective view showing the appearance of an RFID tag-containing apparatus according to the first embodiment of the present invention. Reference numeral 40 in FIG. 4 designates a body. The body 40 is in the form of a foldable wallet. Reference numeral 41 designates a shielded container section. The shielded container section 41 has a container part that can contain several cards C having the size of a commuter pass or that of credit cards. The shielded container section 41 has an open upper part, as viewed in FIG. 4, through which a card can be put in and taken out. Reference numeral 41a designates a flap for covering the open upper part. When the flap 41a is raised, the opening of the shielded container section 41 is exposed. The shielded container section 41 including the flap 41a has been subjected to an electromagnetic shielding treatment. Therefore, the cards contained in the shielded container section 41 cannot be accessed by radio waves from outside.

[0023] Reference numeral 42 in FIG. 4 designates a non-shielded container section. Similarly to the shielded container section 41, the non-shielded container section 42 has a container part that can contain several cards C. The non-shielded container section 42 has an upper end thereof formed with an opening 42a, but is not provided with a flap or lid. Further, the non-shielded container section 42 has an opening 42b formed in a front face thereof, as viewed in FIG. 4, so that a card contained in the non-shielded container section 42 can be viewed through the opening 42b. The shielded container section 41 and the non-shielded container section 42 are joined to each other by a joint 43, as shown in FIG. 4, such that the body 40 can be folded along the joint 43. The body 40 in the folded state can be received in a breast pocket of a shirt or a jacket.

[0024] Reference numeral 45 in FIG. 4 designates an antenna section attached to a lower part of a front face of the shielded container section 41, as viewed in FIG. 4. The antenna section 45 receives a reading signal output from an RFID reader/writer. Further, a microspeaker SP is mounted on the front face of the shielded container section 41 in the vicinity of the antenna section 45. The antenna section 45 and the microspeaker SP are electrically connected to a notification circuit 46 provided in the shielded container section 41, by shielded connection wires, not shown.

[0025] The notification circuit 46 is configured as shown in FIG. 5. Reference numeral 46a in FIG. 5 designates a power generating section that generates and outputs a power generation detection signal when receiving an electromotive force generated by excitation of the antenna section 45 having received a reading signal. Upon receiving the power generation detection signal from the power generating section 46a, a notification signal generating section 46b generates a notification signal for causing the microspeaker SP to sound. When the body 40 constructed as above enters the reading range of a reader/writer to receive a reading signal therefrom, a notification sound is output from the microspeaker SP.

[0026] Next, a description will be given of the operation of the RFID tag container apparatus of the first embodiment. First, the user puts RFID tags or RFID-tagged cards or the like in the shielded container section 41. Then, the user goes to various places with the body 40. If an RFID reader is provided in a place visited by the user, when the body 40 enters the reading range of the RFID reader, the antenna section 45 receives a reading signal. As a result, the power generating section 46a generates the power generation detection signal, and the notification signal generating section 46b generates the notification signal, so that the microspeaker SP generates the notification sound.

[0027] This makes the user aware of the presence of the reader/writer around the user. When the user is e.g. near a check-out counter in a supermarket, a ticket gate in a railroad station, or a gate in an airport, the user can judge that he/she is in a situation where RFID tags are normally read. In this case, the user takes out an associated RFID tag or RFID-tagged card C from the shielded container section 41, and allows the reader/writer to read RFID tag information. Alternatively, the user can move the taken-out card C from the shielded container section 41 to the non-shielded container section 42 to thereby allow the reader/writer to read RFID tag information.

[0028] Even when the notification sound is output from the microspeaker SP, if the user judges that he/she is in a place improper for allowing RFID tag information to be read, the user ignores the notification sound without taking out the associated card from the shielded container section 41.

[0029] As described above, according to the present embodiment, RFID tag or tags within the shielded container section 41 are not yet read at the time the notification sound is output, so that it is possible to prevent important personal information or the like from being read. Meanwhile, in a situation where RFID tag information needs to be read, the user has only to take out the associated card C from the shielded container section 41.

[0030] It should be noted that the notification signal generating section 46b may be provided with a switch 48 for stopping the output of the notification sound. With this configuration, the output of the notification sound can be stopped simply by pressing the switch 48 earliest possible after recognition of the sound.

[0031] Although in the above described embodiment, the shielded container section 41 has a size which allows storage of several cards or the like, this is not limitative, but the shielded container section 41 may be formed to have a larger capacity. Further, the non-shielded container section 42 may not be provided. In this case, when the notification sound is output, an associated RFID-tagged card is taken out from the shielded container section 41 to allow the same to be read by the reader/writer.

[0032] Next, a second embodiment of the present invention will be described.

[0033] FIG. 6 is a perspective view showing the appearance of an RFID tag-containing apparatus according to the second embodiment of the present invention. In FIG. 6, reference numeral 50 designates a suitcase-type body. The body 50 is provided therein with a plurality of magnetically shielded parallelepiped shielded container sections 51 to 54. The front faces of the respective shielded container sections 51 to 54, as viewed in FIG. 6, are exposed on a surface of the body 50. In the exposed faces of the respective shielded container sections 51 to 54, there are provided shutter devices 51a to 54a, respectively. When any of the shutter devices 51a to 54a is opened, an article can be put in and taken out of an associated one of the shielded container sections 51 to 54. Further, when any of the shutter devices 51a to 54a is open, the interior of an associated one of the shielded container sections 51 to 54 is communicated with the external space via its opening, and therefore the shielded container section becomes unshielded. The body 50 is provided with a control section 55, described below with reference to FIG. 7.

[0034] FIG. 7 is a block diagram showing the circuit configuration of the RFID tag-containing apparatus of the present embodiment. In FIG. 7, component parts and elements corresponding to those shown in FIG. 2 are designated by identical reference numerals, and detailed description thereof is omitted. When an antenna section 57 of the control section 55, which is exposed on a surface of the body 50, receives a reading signal from an RFID tag reader/writer, a receiver section 56 generates a detection signal and outputs the same to the CPU 15. The receiver section 56 may be identical in configuration to the power generating section 46a in FIG. 5.

[0035] The CPU 15 supplies a control signal to a selected one of the shutter devices 51a to 54a in response to an operation of the operating section 19 so as to control opening/closing of the shutter device. In other words, the user can operate the operating section 19 to instruct the CPU 15 to open or close a selected one of the shutter devices 51a to 54a.

[0036] Next, a description will be given of the operation of the thus constructed RFID tag-containing apparatus of the present embodiment. First, the user puts RFID tags or RFID-tagged articles in the respective shielded container sections 51 to 54. Then, when the user carrying the body 50 enters the reading range of an RFID reader/writer, the antenna section 57 receives a reading signal. In response to the reading signal, the receiver section 56 supplies a detection signal to the CPU 15 to cause the sound generating section 20 to generate sound.

[0037] The sound generated by the sound generating section 20 makes the user aware of the presence of the reader/writer around the user. When the user is e.g. near a check-out counter in a supermarket, a ticket gate in a railroad station, or a gate in an airport, the user can judge that he/she is in a situation where RFID tags are normally read. In this case, to unshield one of the shielded container sections 51 to 54 which contains an RFID tag relevant to the situation, the user opens an associated one of the shutter devices 51a to 54a by operating the operating section 19. The RFID tag attached to an article contained in the shielded container section having its shutter device opened is read by the reader/writer.

[0038] Even when the sound generating section 20 generates the notification sound, if the user judges that he/she is in a place improper for allowing RFID tag information to be read, the user ignores the notification sound without opening any of the shutter devices 51a to 54a.

[0039] As described above, according to the present embodiment, none of the RFID tags within the shielded container sections 51 to 54 are not yet read at the time the notification sound is output, so that it is possible to prevent important personal information or the like from being read. Further, in a situation where an RFID tag within one of the shielded container sections 51 to 54 needs to be read, the user can unshield only the shielded container section relevant to the situation to make the required RFID tag alone readable.

[0040] The method of unshielding the shielded container sections 51 to 54 is not limited to the use of the shutter devices, but any method may be employed which enables switching between the shielded state and the non-shielded state.

[0041] Further, information designating a shutter device to be opened when the antenna section 57 receives a reading signal may be written in a table TBL2 provided in a non-volatile area of the RAM 17, to thereby allow the shutter device designated in the table TBL2 to be automatically opened when the receiver section 56 outputs the detection signal. In this case, if there is an RFID tag which is frequently read in a certain area, the RFID tag may be stored in a shielded container section associated with opening-instructing information written in the table TBL2. Then, when the notification sound is output, the shielded container section is automatically unshielded without the user operating the operating section 19, and therefore it is possible to save the user's time and labor. Although in the present embodiment, a plurality of shielded container sections are provided, the body 50 may have a single shielded container section.

[0042] The present invention is not limited to the above described embodiments, and can be practiced in various forms.

[0043] Further, the notification sound may be generated using a simple waveform or alternatively a complicated waveform such as a melody or the like. Furthermore, different kinds of sounds may be used for the respective RFID tags. This enables the user to determine, simply by hearing a notification sound, whether or not the sound is generated for an RFID tag for security of which the user should be on the alert. To vary the sounding mode every RFID tag, for example, information on a sounding mode to be used may be written in advance in the table TBL in association with each RFID tag, and the CPU 15 may be configured to refer to the table TBL to instruct the sound generating section 20 to generate sound in the associated sounding mode.

[0044] Although in the above described embodiments, notification is performed using sound, this is not limitative, but light from an LED or the like or vibration from a vibrator may be used. In short, any notification means may be used insofar as it can make the user aware that an RFID tag has been (or is going to be) read.

[0045] Further, the notification means may be provided separately from the RFID tag container section(s). For example, an incoming call tone of a cellular phone or a vibrator may be used as notification means. In this case, radio waves (such as Bluetooth) may be used to output a notification signal. The cellular phone used for this purpose is configured such that an incoming call tone is sounded or the vibrator is driven when the notification signal is received.

[0046] In the first and second embodiments, the notification sound is output when a reading signal from a reader/writer is detected, but instead, the notification sound may be output upon detection of information transmitted in response to a reader/writer reading a freely-readable dummy RFID tag exposed in a non-shielded state.

[0047] Although in the above described second embodiment, the respective shutter devices 51a to 54a of the shielded container sections 51 to 54 are configured to be automatically opened and closed, the shutter devices 51a to 54a may be opened and closed manually. In this case, the user directly or manually operates the shutter device in place of issuing an opening/closing instruction using the operating section 19.

[0048] Further, to unshield the shielded container sections 51 to 54 manually, other various configurations can be envisaged. FIG. 8 shows one example of the configuration. FIG. 8 is a perspective view showing the appearance of an RFID tag-containing apparatus according to athird embodiment of the present invention. Reference numeral 60 in FIG. 8 designates a bag having a pocket section 61. The pocket section 61 is comprised of a container section 61a for containing an article, and a cover 61b formed of a soft material (cloth or vinyl) for covering the container section 61a. The container section 61a and the cover 61b are shielded by respective shielding members. The container section 61a has a parallelepiped space, and a mating surface fastener 62 is attached to all sides of the container section 61a. The cover 61b also has a mating surface fastener 63 attached to all sides thereof. When the mating surface fasteners 62 and 63 are engaged with each other, the container section 61a is fully closed by the cover 61b so as to block a radio wave from being transmitted into or out of the container section 61a.

[0049] The antenna section 45 and the microspeaker SP are arranged in the vicinity of the pocket section 61 in a state exposed to the outside, and the notification circuit 46 is provided within the bag 60. This arrangement of the present embodiment is identical to that shown in FIG. 5.

[0050] With the arrangement described above, the user puts a RFID tag or RFID-tagged article in the container section 61a and closes the container section 61a with the cover 61b. Then, when the bag 60 enters the reading range of an RFID reader/writer, the antenna section 45 receives a reading signal, and a notification sound is output from the microspeaker SP. When the user hears the notification sound and judges that he/she is in a proper place where the RFID tag is normally read, he/she opens the cover 61b to electromagnetically expose the container section 61a, and allows the RFID tag within the container section 61a to be read. If the user hears the notification sound in an improper place for allowing the RFID tag to be read, the user leaves the container section 61a covered by the cover 61b without opening the same.
